Side chain interactions protein structure

WebFor example, R groups with like charges are repelled by each other and those with unlike charges are attracted to each other (ionic bonds). Uncharged nonpolar side chains can form hydrophobic interactions. Interaction between cysteine side chains can lead to the formation of disulfide linkages. Figure 2.27 Tertiary Protein Structure. Web1 day ago · It was hypothesised that the structural basis of these opposed functional effects might be the straightening of transmembrane helix 5, which is kinked in the wild-type protein. In this study, we present the functional and structural implications of the mutation P208R in the archaeal homologue of glutamate transporters GltTk.
